Can polyacrylamide be removed from offshore oilfields before discharge?

Due to the severe restrictions imposed by legislative frameworks, the removal of polyacrylamide (PAM) rapidly and effectively from produced wastewater in offshore oilfields before discharge is becoming an urgent challenge.

What is polyacrylamide (PAM)?

Polyacrylamide (PAM) possesses unique characteristics, including high water solubility, elevated viscosity and effective flocculation capabilities. These properties make it valuable in various sectors like agriculture, wastewater treatment, enhanced oil recovery, and mineral processing industries, contributing to a continually expanding market.

What is a polyacrylamide & oligomer?

Polyacrylamide (PAM) & oligomers PAM is a water-soluble, odorless, white synthetic linear polymer with the repeating formula (-CH 2 CHCONH 2 -), and its monomer used is AM. Its molecular weight (MW) of PAM ranges from 10 5 to >10 7 Da, with a length of up to six million monomer units.

How dangerous is polyacrylamide (PAM)?

4.1.1. Polyacrylamide (PAM) As PAM is extensively used in our daily lives, it is essential to be aware of its potential hazards. Studies have indicated that PAM exhibits low or non-toxicity to humans, primarily due to the large sizes of polymers, which restrict their ability to penetrate the skin.

Does a partially hydrolyzed anionic polyacrylamide remove Pam?

A partially hydrolyzed anionic polyacrylamide with a molecular weight of 2.2 × 107 Da was used as the model compound, and the PAM removal efficiency was evaluated under different conditions, including discharge voltage, initial solution pH and the co-existence of other pollutants.

How to treat partially hydrolyzed polyacrylamide wastewater?

Treatment of partially hydrolyzed polyacrylamide wastewater by combined Fenton oxidation and anaerobic biological processes Surface and subsurface requirements for successful implementation of offshore chemical enhanced oil recovery Wetted-wall corona discharge induced degradation of sulfadiazine antibiotics in aqueous solution
